1 Claim.

My invention relates to window draft shields and has particular reference to shields or dellectors used in connection with house windows which are opened for ventilation.

The object of my invention is to provide a shield which can be conveniently attached to a Window casing for dellecting and breaking the draft when the lower part of the window is opened for ventilation. Another object of my invention is to provide a shield Which can be adjusted for windows of different width. Still another object of my invention is to provide a shield which can be inclined to a varying degree for adjusting the width of the air passage between the window and the shield. Other important features of my invention reside in the simplicity of its construction and arrangements for resilient clamping of the glass panels in the telescoping frame. These and other features of my invention are more fully described in the accompanying specication and represented in the accompanying drawing in which- Fig. l is a perspective view of my shield attached to a window, Fig. 2 is a top View of the bracket, Fig. 3 is a side view of the same, Fig. 4 is a sectional View of the bracket with the glass panel, Fig. 5 is a longitudinal sectional View of the frame with a portion of the bracket and of the panel, Fig. 6 is a partial sectional view of the frame in its telescoping portion, Fig. 'l is a section taken on the line 1--1 of Fig. 6, and Fig. 8 is a detail view showing a section of the upper portion of the bracket.

My shield or ventilator consists of two panels I preferably made of glass plates overlapping each other in the middle and supported on top and bottom by telescopic rods or channels 2 and 3. 'Ihe ends of the plates are held in similar channels in end brackets 4. The end channels are formed by bending back the edges of the brackets and attaching angles 5 to the sides of the brackets. The edges of the channels in the brackets and in the rods 2 are bent inwardly at an angle forming resilient lips 6, shown in Fig. 4, and similar resilient lips 8, shown in Fig. 7. The channels are preferably made of a thin, resilient metal. The lips 6 are cut away at the ends of the bracket channels in order to form recesses I for the ends of the rods 2 and 3. The top of the bracket 4 is bent over the recess l thereby formf ing a closed place for holding the ends of the rods. The channels or rods 3 are slidably iitted in the channels 2 and have rounded off edges 8' tting in the inside curved portions of the lips 6 as shown in Fig. 7. With this angular shape of the lips they are adapted to resiliently hold the glass panels by their inner edges resting against the glass. They are spaced so as to hold tightly the double thickness of the glass in the middle as shown in Fig. 7. The end portions of 5 the glass plates are held by the lips 6 in the bracket channelsA which are spaced closer together than the lips 8.

The brackets 4 are made narrow at the bottom and are connected by pivots or rivets 9 10 with plates IIJ. The latter have holes II for attaching them to the inner sides of the Window casing I3 by screws I2. Slots I4 are provided in the brackets 4 for the .screw heads. A hook I5 is formed at the upper edge of the bracket 4 en- 15 gaging the upper edge of the plate I0. This edge is curved so as to facilitate the sliding movement of the hook I5 when the bracket is turned on its pivot. Lugs I6 are formed at the upper corners of the plate Ill for limiting the movement of the 20 bracket 4. In order to provide a clear space for the movement of the hook I5, the plate I0 has outwardly projecting ribs Il which can be stamped out of the material of the plate. Thesel ribs also serve to stiffen the plate. The pivots 9 25 and the hooks I5 provide sufcient friction so that the bracket 4 with the channels and plates I can be placed into any position between the lugs I6 and will retain this position. The turning can be accomplished by merely pulling or pushing 30 the upper ends of the brackets 4.

The parts I, 2 and 3 can be made in uniform sizes, and the complete assembly can be fitted to windows of any width Within practical limits. For assembling the shield the lower channels 35 are placed rst in their correct position, tting the ends in the lower ends of the bracket channels, after the brackets have been ltted to the window casing. The glass panels are then slid between the end channels and tted into the lower 4.0 channels. The upper channels are then placed in positionvover the glass, fitting their ends into the recesses or sockets 'I. By pushing or pulling the brackets the area of the air circulation can be varied.

The air draft, howeverV strong, cannot cause the glass plates to rattle, as they are securely held between the resilient lips 8 in the Overlapping portions, while the ends of the plates are also clamped between the resilient lips 6 in the brack- 50 ets. The clamping effect is increased by the angular shape of the lips so that they rest against the glass by the sharp corners of the edges of the metal of the channels.

The construction of my window shield or ven- 55 tilator can b`e modied in minor details, of course, Without departing from the spirit of my invention. Certain minor details can be also omitted.

`For instance, the top and bottom channels, While Y can be made chiefly of simple metal stampings in standardized sizes, with glass plates also of standard sizes; it can be shipped in a disassembled condition, and can be easily assembled on Windows by the purchaser. The channels 2 and 3 are made of uniform sizes, having rounded edges adjacent to the glass, which facilitate their handling and improve their appearance. The angular shape of the edges on the channels 2 and 5 tend to increase their resiliency and to provide a stronger grip on the glass plates.

I claim as my invention:

In a Window draft shield, the combination with plates adapted to be attached to the sides of a Window casing, brackets pivotally connected with said plates at their lower ends, the upper ends of said plates being curved concentrically with said pivots, the upper ends of said brackets being provided with hooks engaging the curved ends of said plates, lugsat the ends of said curved edges limiting the rotational movement of said brackets, stiffening ribs on said plate adapted to keep the upper edge away from the Wall of said casing so as to provide room for the movement of said hook, channels attached to the inner sides of said brackets, telescopic channel-shaped rods supported by their ends in said channels, and glass panels slidably overlapping each other and supported by their side edges in said rods and by their end edges in said channels.
